NATURAL-GAS HEATER FOR FlRE-PLACES.

SPECIFICATION forming part of Letters Patent No. 386,391, dated July 17,1888,

Application filed February Q5, 1588. Serial No. $65,255.

To all whom, t may concern.:

Beit known that I, JOHN M. ELLIsoN, a citizen of the United States, anda resident of Allegheny City, in the county ofAllegheny and State ofPennsylvania, have invented certain new and useful Improvements inNatural-Gas Heaters for Fire-Places; and I do declare the followingto bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specitication.

Figure l of the drawings is a representation of a front elevation of myimproved fire-place. Fig. 2 is a vertical section on line m, Fig. l.Fig. 3 is a vertical section through one end wall. Fig. ais a top viewof chamber D.

The object of this invention is to provide apparatus of economical andeffective character for heating and Ventilating houses or apartmentsthereof; and the invention consists in the construction and novelcombinations of devices,all as hereinafter set forth, and pointed out inthe appended claims.

In the accompanying drawings, the letter A designates a fire-placehaving hollow side walls, B, and back wall, C, and provided also withthe hollow sloping top D, which is sepaated by the throat V from thetransverse connection or girder Il, which is preferably of arched formand extends across from the front portion of one of the hollow sidewalls to the front portion of the other; and I sometimes provideatransversc vertical partition between the front portion of the chamberin said side wall and the back portion, dividing the same into a frontlue, F, and a back flue, G, which communicate by the opening a in saidpartition. Gold air is conducted into said chamber or flues and entersat the inlets b b, near the lower ends of said chamber or iues, asshown. When the back wall, C, is hollow, as preferred, it is designed toprovide an opening for communication near the top of the back wall ateach side thereof, as at c c, whereby the air may enter the back chamberfrom the side chambers. A tubular passage, d, leads from the backchamber to the sloping chamber H in the hollow inclined top D, whichcovers in the back portion of the tire-place, as

shown. Openings c e are also made at the ends of the hollow top in thefloor thereof, to admit hot air Afrom the chambers or rear tlues of theside walls. Usually I. provide ribs K K in this top tlue between the endportions and middle thereof to strengthen the parts. rIhese ribs,however, have passages at g g, whereby communication is establishedbetween the end portions and middle part of said sloping chamber. In thebott-om or floor of said sloping chamber is also an inlet, h, whichreceives the end of a pipe, k, whereby con'nnunication is establishedbetween this sloping chamber and the hollow heater L, which is securedin the tire-place. This heater is designed to be ot' sectionalconstruction and to have somewhat the appearance of a coil or grating.Usually I provide two coils, N N, which are arranged side by side, andare provided with laterallyextending pipes or conneetionsl, which engageopenings in the inner walls of the tire-place at the sides thereof. toestablish communication between the side tlues or chambers and thesectional heaters. These heaters are also provided with rearwardly andupwardly extending pipes or connections m, which may be again connectedby a union, c, from which a pipe, 7c, extends to the top chamber, or thesingle pipes m may connect directly with the ioor ofthe top chamber.

In building the heater it is preferred to use short pieces of straightpipe, as at a, and elbows or unions e, into the ends of which thestraight pieces of pipe are secured, each section forming, as indicated,a sort of coil, preferably, through which the air from the chambers inthe side wall courses, being heated in its passage by the llames of thenatural gas or other combustible which play around and about the heaterL, raising said heater to a high temperature. The air thus heated passesupward into the chamber in the sloping top D, and being there mingledwith the warm air from the hollow back and sides of the ireplace, may beconducted off through openings l s and suitable pipes or passages inconnection therewith to heat other apartments, while the apartmentinwhich the lire-place is located is heated by the burning gas and theheater L, whose temperature is raised thereby. The burner-opening forthe natural gas is indicated at J. I is the spreader. For Ventilatingpurposes it is designed to provide, in connection with openings in thefront walls of the side fines of the fire-place, registers R, which maybe regulated to graduate the ad mission of air from the room intotheseside chambers, according to requirement.

Having described this invention, what I claim, and desire to secure byLetters Patent,

1. In a fire-place for natural gas having `hollow sides and top, asectional pipe heater,

L L, in said re-place having lateral pipe-connections leading to saidsides and upwardlyextending pipe-connections leading to said top,substantially as specified.

2. The combination, with areplace having natural-gas burners and hollowside walls, of
